After graduating from Kyushu University in 1994, Kiyomasa Nishii made several genetically modified mice in the laboratory of Professor Yosaburo Shibata at Kyushu University to study mammalian development and received a PhD in 1999. In 2005, he moved to the laboratory of Professor Shigeo Okabe at Tokyo Medical and Dental University and later to the University of Tokyo to examine the neurobiological findings of the mice he created. Since 2009, he has been studying the axonal projection of mutant retinal ganglion cells together with traumatic brain injuries after exposure to blast-induced shock waves in the laboratory of Professor Yasushi Kobayashi at the National Defense Medical College. Since 2015, he has been an associate professor at the current laboratory. His research focuses on observing fluorescent markers that are expressed or incorporated into living animals at macro to microscopic levels.
